ENGINE-FRAME JIG.

SPECIFICATION forming part of Letters Patent No. 349,757. datedSeptember 28, 1886.

I Application filed .Tune 4, 1885. Serial No. 167,662. (No model.)

To all whom, it may concern:

Be it known that I, LE GRAND SKINNER, a citizen of the United States,residing at Erie, in the county-of Erie and State of Pennsyl Vania, haveinvented certain new and useful Improvements in Engine-Frame.Templets orJigs; andI do hereby declare thefollowing to be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, forming part of this specification.

My invention relates to improvements in engine-frame templets; and itconsists in the mechanism hereinafter set forth and explained in. thespecification and claims.

My invention is illustrated in the accompanying drawings, in whichFigure l is a perspective view of my improved engine-frame templet orjig with parts thereof detached. Fig. 2 is a perspective of thecylinder-head face-plate thereof. Fig. 3 is 'a perspective view of thedetachable rocker-shaft templet mechanism thereof. Fig. ivshows a collarto be placed in front of cylinder-plate. and 6 show details.

Similar letters refer to like parts in all the figures.

In the construction of my improved tem-.

plet or jig, B is the main supporting rod or frame thereof. Firmlyseemed to one end of the rod 13 is a cross-piece, A A, adapted to beplaced in the pillow-block boxes of an engine. This cross-piece A A isprovided with fixed collars a a, and also with loose collars a a,adapted to fit against the inner and outer ends of thepillow-blockboxes, so that molten babbitt may be poured into the boxes over thecrosspieces A A for fitting the same for the shaft. Securely attached tothe central part of the rod B are also blocks or bearings G G,'providedwith holes g 9, adapted to receive, line up, and sustain the guide-boltswhile the same are being babbitted into place in an. engine-frame.Glamped to the rod B between the blocks G G is also an arm, H, which iskept from turning on the rod B by the fin h. The lower end of the arm His provided with a cross-sleeve, H, and set-screw 71, this sleeve Hbeing adapted to receive and support the rocker-shaft telnplet-rod H",for lining up and babbitting the rocker-shaft boxes on an engine-frame.

On the end of the rod .13, opposite the pillow-block cross-piece A A, Iplace a recessed with a set-screw, e, and is adapted to slip on theendof the collar D and leave some space between a portion of saidsleeve Dand the outer end of the collar E, so that the collar E is adapted tofit over the end of the sleeve 1) and against the end of thecylinder-head, where it is secured in place by the set-screw e operatingagainst the supporting-rod B.

On the outer end of the supporting-rod B, I place a face-plate, O, whichis provided with a long sleeve, O, adapted to fit the rod B closely andslide thereon. The face of the plate 0 is adapted to be shoved upadjacentto the face of the cylinder-head" and against the end of thesleeve D, substantially as shown in Fig. 1, when it may be secured by aset-screw (not shown) upon the supporting-rod 13. Holes 0 are alsoprovided in the face-plate O,

into which templet-pinsc may be placed,

which will pass through openings for the boltholes in thecylinder-head;lthese templetpins 0 being provided withsliding collars0', adapted to fit against the outer end of the cylinder-head,and'having set-screws therein for securing themin placeythisface-platemechanism being .so arranged that when in place on an engine-framemoltenbabbitt or other metal maybepoured between the same and saidcylinder-head,'and the same thereby turned up in line with otherbearingson the engine-frame, and thereby finished ready for the reception of acylinder and stuffing-box.

In the drawings I have shown a simple and convenient form of templet orjig for the purpose specified. However,-I donot desire to limit myselfto the peculiar form of construction shown, as it is obvious to thoseskilled in the art to which it appertains that it can readily beconstructed in many different shapes and good results obtained therewithwithout in any wise departing from the spirit of my invention.

Having thus fully described my improvement and the adaptation of itsseveral parts, its operation will be obvious to those conversant withthe art to which it appertains without further description thereof;therefore,

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. In a templet or jig, a cross-bar adapted to rest in the pillow-blockboxes of an engineframe, provided with and having attached thereto arigid rod or frame extending to or beyond the cylinder-head on suchengineframe, in combination with a movable faceplate adapted to coverthe face of such cylinder-head, and'to be adjusted thereto on said rodor frame so as to line up with the pillowblock boxes, substantially asand for the purpose set forth.

2. The combination, in a templet or jig, of a crossbar adapted to restinthe pillow-block boxes of an engineframe, and a rigid rod or frameattached thereto and extending to the cy1inder-head on suchengine-frame, wit-h bearings or supports on said rod or' frame, to whichthe guide-bolts may be adjusted and lined up with the pillow-blockboxesand the cylinder-head on an engine-frame, substantially as and for thepurpose set forth.

3. The combination, in a templet or jig, of

a supporting-rodprovided with a cross-piece adapted to fit thepillow-block boxes of an engine-frame, with a face-plate adapted tocover the face of a cylinder-head on said frame, templet-pins adapted topass through cylin der bolt-hole openings,'and a collar and sleeveadapted to pass through the stuffingbox in such cylinder-head,substantially as and for the purpose set forth.

4. The combination, in a templet or jig, of a supporting-rod providedwith a crosspiece adapted to be placed in the pillow-block boxes of anengine-frame, and with an adjustable cylinder-head face-plate adapted tocover the face of the cylinder-head on such engine-frame, with bearingsor supports attached to said rod for adjusting and sustainingguide-bolts, substantially as and for the purpose set forth.

5. The combination, in a templet or jig, of a supporting-rod providedwith a pillow-block templet-rod, an adjustable cylinder-head face-plate,and guide-bolt supports, with an arm on said rod supporting arocker-shaft templet-rod, substantially as and for the purpose setforth.

In testimony whereof I affix my signaturein presence of two witnesses.

LE GRAND SKINNER.
